I remember reading an article in backpacker magazine about this topic from the standpoint of limiting effect on the environment, packing out etc. The author of the article noted that she (yea female writing about this topic) had harder bm's due to diet, chance in water consumption with increased perspiration and she would purposely hold as long as she could comfortably stand it. She noted her bm's were much dryer and did not have to use a lot of tp.
Liked the idea of generic baby wipes.
Also I see a lot of us going to the cloth method at some point. It also stores flatter than tp and will be one of the uses for clothing that has worn out.
